Fisher "Uranium Scout" (1950 - 1955)

The “Uranium Scout” Model T was a neat looking prospector’s GM manufactured by the Fisher Research Laboratory, Inc. of Palo Alto California.   There is a small check source in a plastic holder that is fixed by a chain to the case. The instructions with the check source read: “Scout: Place at center slot on side of box.  Scout De Luxe: Place over test spot on probe.”  Since the probe has a small black test spot on the side, and since there is no slot on the case, it would seem that this is the “Scout De Luxe.”  There are two controls: a range switch (Off, x1, x 10, x100) and a sensitivity/calibration adjust.

Detector: Aluminum thin-walled GM tube (Victoreen 1B85) enclosed in bakelite probe that attaches to the side of the case.

Range:  0 – 500, 0 – 5,000, 0 – 50,000 cpm

             0 – 1, 0 – 10, 0 – 100 ore concentration (percent?)

Audio:  No speaker, but comes with headphones

Size:  4” x 7.5” x 4.5”

Batteries: two 1.5 volt, one 45 volt and one 67.5 volt
